,To allwhom z't vmay concern Be it `[known that I, :lim T. HOWARD, a citizen of the United States, `residing Lat Goshen, inthe county of :Elkhart andState `of Indiana, have invented new `and useful Improvements in illaners, of .which lvthe {following is `a .speeiieation My linvention .relates @to `improveinents in tplaners, and `,is especially adapted #to iplane or dress stereotype f and Wood mountedf'euts ito' `type height, .although its objeet is ,not `limitedfto that-elhfit being understood that onefofgitsmost important obj ents `istheplanlingfands finishing` ofthe. surface. of anyLmetal which y can f be i filed.

Another .i mportant. obj eet. of my invention .is the ,planing and dressing yof lumber `iin which art it Eis `highly edeetive, being very muoh more 1 efficient iin :the dressing of hard wood lumber than Y,the ordinary planer. Vhere lumber is yilrnotty, or irregularly .fgrainedithe knots are smoothly plandfflush ,with kthe surrounding surface Without .shattering the knot or rippingit=from"rtl1ezlum ber, `aiuildthe irregularly grained dumber is ,readily planed :to a ,smoothginish and without n detaehing :and ihurling ,splinters :therefrom. liffthe luniberoarries nail or lsorevv :fragments therein any invention readily redueesiand les Athem down `flush `with the .surrounding `surface lWithout injury to the fiile .or ra-sp member.

2. The numeral G designates a frame top lplate extendingtransversely of frame members `1 `and y2 and having; its oppositeends secured thereto adjaeentthe upperierminals `ofguides 4,14. Thenumerals 7, 7 designate Shaft boxes lslotted at 8, 8 and slidably arranged Within the guides 4,4- oneaeh 'frame member -l `and Q, `and provided with the transverse shaft bearings 9, 9, preferably fforinedof some antifriction metal, and rigidly `fastened in Vopenings formed in @the boxes l7, 7.

.The nun'leral 110t designates a rotary oylndrical planer member theoutenor eircumiferential, periphery of which `constitutes a lfle or 1 1asp,of any desired degree of ineness or coarseness, iprovided `with the end shafts 1K1 and 12 ,which are journaled Within the bearings 9, 9 and adapteddzo be rapidly rotatedabya pulle,7 '13 rigidly -fastenedto'the end ofshaft member 12ste whielrpovveranay be applied by belt, or otherwise. The numorals 1&1-, il-l designate adjustable .screws .carried `inthreaded openings in each 4.frame member l and -Q and bearing against 4ithe under side or surface of the boxes f7, i7 ifor Lupwardly 111.0 ving, or adjusting, same Within :theguides Ll, Il.

The numeral 15 `designates a spring seat bossoirthe upper surface ofeaehbox 7, and a corresponding spring .seatfboss on `the ,un der surface of each end of' the top plate@ isdes- .ignated vby the numeral 11G, around which bosses the tension springs 17, i7 lare seated andbear againstthe-boxesl 7, 7, being adapted to downwardly impel the bones27, 7 .when .the adj ustino screws i4, 14 are retracted.

The numerals ifi, .18 indicate sereivsfoarfried intlireaded apertures in each` endofthe top plate 6 centrally of the boss 16andavithin the-spring,` :17a11d adapted `to besorevved into rigid engagement with the-bearing box iboss 15, subsequent tothe adjustmentof the box 7 by the :manipulationof the adj Listing screws Ll, 14, to render the abrasive ement ber l() unyieldable for service. i'llhe numer- -als :1.9, 119 designate carriage `ruido rods se- Cured in :apertures formed in (the end frame members 5, 5 in any suitable `manner :for supporting and guiding the carriage 2O which is provided on its under surface with 4suitable half :boxes 2l, 2l in slidable en- -,g'agenient lwith said rods 19., 19. The :oar-

f cally bored for its full length for detachable` arrangement upon a conically formed ile` riage 20 is provided at one end with a handle 22 to manually operate it along the guide rods 19, 19 and back and forth thereon beneath the rotatable le 10.

The numeral 28 designates a transversely disposed stop piece secured to one end of the upper surface of the carriage 2O against which the member to be planed is placed. The numeral 24 designates a slot formed longitudinally of the carriage and therein, within which is slidably mounted a thumbscrew 25 which is carried by a transversely disposed locking member 26 adapted to be moved along the carriage surface and placed against the back end of the member to be planed to rigidly retain it in position on the carriage by screwing the thumbscrew 25 tightly against the member 26. The thumbscrew 25 is provided with a head 25 which is arranged on the under side of the slot 24, and impassible thereof, projecting through said slot 24 and is threaded into an aperture formed in the lock member 26. The numeral 27 designates a curved transversely disposed guard plate suitably secured to the guide uprights of the frame members 1 and 2 in front of the file 10 and extending downward toward the carriage surface to prevent contact of the operators hands withthe rotating file 10. In Figs. 4 and 5 the numeral 28 designates a cylindrical rotatable rasp cooperating with the cylindrical file 10, driven by gears 29, 30 and 31 meshing into each other, gears 29 and 31 being mounted upon the shaft ends of files 10 and 28, respectively, and idle gear 30 being suitably mounted upon a pin or shaft 32 carried by one of the boxes 7, 7 and movable therewith. Gears 29, 30 and 31 preferably have the same number of teeth to drive the rasp 28 at a speed equal to that of the file 10, the idler 30 being provided to obtain the same direction of rotation for both abrasive members 10 and 28.

At Fig. 8 is shown a modified file structure consisting of a cylindrical file 10 conicore 33, circular in cross section, and retained thereon by a collar 34 screw threaded on one end of the shaft, or lile core, 33 at 35.

In the practical application of my invention the article to be planed or dressed down is secured to the upper surface of the carriage and the file rapidly rotated by the application of power to the driving pulley. By moving the carriage back and forth beneath the rotating file at a height where the le and the article to be planed are placed in contact, the latter may be planed 0H to any desired thickness.

I claim,

3. In a device of the kind described, in combination, a frame havingside upright box guides, vertically yieldable journal boxes mounted in said upright box guides, acylindrical rotatable rasp j ournaled in saidj onrnal boxes, a pair of longitudinal rods connected to said frame in parallel relation, a platelike carriage, a fixed and a longitudinally adjustable stop piece carried by said carriage upon its opposite ends. a handle on said carriage, and depending members on said carriage having curved portions straddling and slidable upon said rods.

4. In a planer, a mount, a plurality of rotatable abrasive members carried by said mount, means for unyieldingly holding said rotatable abrasive members, said members being also rendered yieldable vertically, the abrading surfaces of said members being graduated in quality as to each other, and a planer carriage adapted to carry the object yto be planed under said members.

5. In a device of the kind described a frame, an abrasive member, vertically adjustable means for holding said member rigidly against movement, said means being disposed upon said frame, and a slidable carriage guided for horizontal movement beneath said abrasive member.

6. In a device of the kind described, in combination, a mount, bearings thereon, journal boxes vertically slidable in said bearings, a cylindrical file carried by said journal box, vertically adjustable members bearing against the upper and lower portions of each journal box to hold the cylindrical ile unyieldable, and resilient means arranged to engage said journal boxes and adapted to yieldingly support said Cylindrical file When either of said adjustable members is out of Contact With either of saidjournal boxes.

7. In a device of the kind described, in combination a mount, bearings on the sides l0 thereof, journal boxes in said bearings slidnal boxes, a longitudinally slidable carriage l5 beneath said rotatable file, and a stock conlinmg member carrled by said carrlao'e.

`In testimony whereof I hereunto af-ix Iny signature.
